One milligram (mg) of protamine sulfate will neutralize approximately 100 units of UFH. This calculator determines a neutralizing dose of protamine to reverse both UFH and LMWH in the non-surgical setting based on the anticoagulant to be reversed, the anticoagulant dose, and the time that the anticoagulant was last given. It is not appropriate for pediatric patients or for an operating room setting (such as cardiovascular surgery). 3, 4 This calculator is intended to dose protamine in adults patients on a medicine floor and in the ICU. The rate of administration of protamine should not exceed 50 mg in any 10-minute period since administration that is too rapid can cause severe hypotensive and anaphylactoid-like reactions.Protamine sulfate, a derivative of fish sperm, is commonly used for the reversal of anticoagulation effect of unfractionated heparin (UFH) and low-molecular weight heparin (LMWH). The half-life of enoxaparin should be taken into account when calculating the neutralizing dose of protamine to avoid overdosage. Particular care should be taken to avoid overdosage with protamine. The dose of protamine should be identical to the dose of enoxaparin injected, that is, 1 mg or 100 units of protamine to neutralize the anti-IIa activity generated by 1 mg enoxaparin. injection of protamine will almost completely neutralize the anticoagulant activity of enoxaparin (i.e., the anti-IIa activity) however, the anti-Xa activity is only partially neutralized (maximum about 60%). The anticoagulant effect of the drug is inhibited by protamine. I still wanted to put it out there so other new nurses may benefit.SarahPer the Cleaveland clinic it's 1mg of Protamine SIVP for 1 mg of Lovenox.įor treatment of overdose:Protamine (either the sulphate or hydrochloride salt) should be administered in more serious cases.
I'm sure since this post is so old you've come a long way in your practice. from another country online told me it wasn't".
Think if it this way, you're sitting in court, your patient bled to death and the attorney says you didn't know protamine sulfate was the antidote? You say, "well I thought I did but this dr. It doesn't matter if they're a doctor from the US, another country, or another planet, you need to be sure because it's your practice and not theirs. Including your sources sources if needed. Always check your sources and information.
Warfarin-vitamin k, ffpĭo you have some additional info? pls share it! thanks! :typingĪctually, and I know this is old but I teach nursing and hate to see information that's incorrect, but Protamine is used to neutralize Lovenox.
